The refrigeration systems in food stores and supermarkets continuously operate to maintain proper food storage temperatures. During the operation, the evaporator coils require periodic defrost, which poses adverse impact on food safety. This study attempts to explore methods of minimizing the number of times these units go through the defrost cycle. The research focuses on using coils with hydrophobic material properties to repel moisture and a demand-defrost controller for walk-in freezers that activates the defrost cycle only when frost forms on coils and not at usual prescribed periods.
